Here's my latest project!! Remington 700 6.5 creedmoor.

So i made a dummy round with small base full sized. Still wont fit on the hornady but check all diameter and within the cartridge specs as per the book. I tested it to the rifle to see if it will chamber and it did. So i guess my gauge is shitty. At least now i kmow it will chamber and can be extracted easily. Thanks everyone for the inputs.

Great info thanks for the vid!

Fellas another problem i'm having with my .308 reloads. I have Lee full sizer and RCBS small base sizer. I also have this Lyman Case Length Headspace Gauge 308 Winchester and this Hornady Cartridge Gauge 308 Winchester. So at first I resized my LC brass and some brass fired from my rifle with the lee. I checked them with the hornady gauge and the won't go all the way in even if I use the small base sizer. But when i check the brass with the Lyman, they go in with no problem. Any ideas why? I'm getting frustrated since before i had a round stuck in my chamber. Thank you in advance for the help..

Enough has been said regarding loose primer pockets, improperly swaged primer pockets and over pressure situations. I have nothing to add about this.

With that said there is a condition no one has addressed and I will address it here as I reload using low pressure loads and I see this quite often. It has been written that when shooting low power loads the pressure is not quite enough. In this particular situation it is said that under a normal pressure situation when lit off the case expands and is pushed back against the bolt face. Primer will show normal. But under a proper low pressure load the case expands but there is not enough pressure to push it back against the bolt face. And the primer will pop out slightly. I have shot tens of thousands of rounds with primers popping out slightly. So the question remains will raising the pressure relieve this condition? I can say with my testing it is quite true. But I should say that this only applies to a firearm that is properly headspaced.

I believe that the fact that only some of your reloads show this condition proves this as this is exactly what I see when my low pressure loads are on the border between low and normal pressures. A lot of this will also depend on barrel, chamber, barrel condition, case thickness, bullet diameter, charge weight, etc. All of these things are different between each and every cartridge. Also, the fact that your bolt didn't hold open on a load or two makes me think you are just at that point between low pressure and normal pressure. My suggestion is to try more loads with the same cases, primers and bullets and raise the charge weight 0.50 grains and maybe 1.0 grains. I think you'll not see this not occur any more. Again, assuming your rifle is headspaced properly.

One more thing. I believe that 3031 is the right burn speed for 55 grain bullets in that cartridge. I have found through my testing that 3031 was not the best powder for the bullet, powder, primer, case, rifle combination I am using. It may work really well for you. If you want to try another powder I recommend H335 for that weight bullet as it is just a tad bit slower. And I found better consistency and higher velocities with H335 over IMR 3031.

I remember one of the range master mentioned about too low of a pressure or charge when i showed my case to him. I will try and experiment some more. Thanks everyone for the input.

Personally, I use the crimp remover in my electric drill. https://www.amazon.com/gp/product/B0063IDE6A/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

The Hornady manual says 20.5 but there's little tolerance with the 223. With my rifle, 18 gn won't cycle the bolt with some powders.

Yeah i think 20.5 is too light because after my last round, the bolt carrier doesn't even lock. So far that the only problem i had with my first batch of reload.

Please post some pictures of the cases and the primers.
 Also 20.5 gr. of which powder? What is the length your finished round?
Are you checking each case for charge weight?
Are you using a crimp?
Are you shooting bolt action or semi auto?

20.5 gr IMR 3031. Finished round is 2.25. Not using crimp and also didn't check  the weight. I am shooting semi.

amazing how you reload from that angle - very talented 

I want to put it on the front but my wife said its in the way so i have to put it on the side. It worked out great though since the trash is right under the press so the primer goes straight to the trash can.

Here's mine. First time building a work bench.

I just started reloading too and the decapping pin on my die got bent on my 10th brass. Used a Lee lube that came with my kit and 500 case later and no stuck case.
